Capsicum annuum · PhytoNexus

01 Identity and provenance

Accepted binomial: Capsicum annuum
Common names: Chilli
Family (APG IV): Solanaceae
Part used: Fruit
Verification tier: Tier 1 · chemistry only Taxonomy, plant part and marker chemistry are populated and stable. The clinical columns are deliberately empty because no primary source has been retrieved for them yet. Interactions shown below are rule predictions from the constituent chemistry, not clinical findings.
Reviewer note (2026 audit): TIER 1 populated (name, family, part, constituent class, marker) - stable taxonomic/phytochemical facts. TIER 2 columns (analogue, application, brand, interactions, side effects) left blank BY DESIGN - populate only from retrieved primary literature. Do not use clinically until Tier 2 is filled and a reference is recorded.

02 Constituent chemistry

Chemical class	Marker compound	Synthetic analogue in use
Capsaicinoids	Capsaicin Fruit	none listed

The analogue column is what makes the interaction reasoning tractable: where a constituent has a marketed structural counterpart, the counterpart's interaction profile is the starting hypothesis for the plant.

03 Stated application

Left empty by design — this is a Tier 1 entry, and the clinical columns are only populated once a primary source has been retrieved for them.

04 Interaction matrix

Predicted from constituent chemistry

These edges are not clinical findings. Each one is a rule inference: a constituent class in this plant is known to act on a target that the drug class also acts on. They are shown because a blank cell reads as “safe”, and for a Tier 1 entry a blank cell only means “not yet looked at”. Treat them as a literature-search agenda, not as a warning.

Chemistry of this pair. Capsaicinoids are TRPV1 agonists causing neurogenic inflammation and increased cutaneous permeability. Class mechanism. Salicylate-, coumarin- and eugenol-bearing botanicals add both antiplatelet activity and direct gastric mucosal irritation to cyclo-oxygenase inhibition; several also reduce renal prostaglandin-dependent perfusion. Expected Peptic ulceration, upper GI bleeding, acute kidney injury in volume-depleted patients. Management Avoid in ulcer history. Add gastroprotection where the combination is unavoidable, and monitor renal function in the elderly.

Chemistry of this pair. Capsaicinoids are TRPV1 agonists causing neurogenic inflammation and increased cutaneous permeability. Class mechanism. Essential-oil terpenes, capsaicinoids and phorbol-type diterpenes add to the barrier disruption caused by topical antiseptics, retinoids and keratolytics, and increase percutaneous absorption of anything applied with them. Expected Contact dermatitis, chemical burn, photoirritation, unexpected systemic absorption from broken skin. Management Patch test first. Never apply undiluted essential oils to broken or freshly shaved skin, or with occlusion. Onset rapid Evidence D - in silico rule prediction only Find evidence for this pair Map this mechanism

05 Hazard register

The audit recorded no hazard beyond the interaction profile. The controlled-vocabulary field reads not assessed, which means the assessment has not been done rather than that it came back clear.

06 Confusable material

No same-genus or shared-common-name entry in the corpus.

09 Isomechanistic neighbours

Species whose interaction profile overlaps this one, ranked by shared severity weight rather than by count — a shared contraindication counts for more than a shared minor signal. Practical use: these are the plants you should not stack with this one, because the mechanisms summate.

10 References and notes

No citation is on record for this entry. That is itself the finding: the audit flagged it, and it is why the entry does not carry an A evidence grade.
